Narrated `Aisha
I used to wash the traces of Janaba (semen) from the clothes of the Prophet (ﷺ) and he used to go for prayers while traces of water were still on it (water spots were still visible).
Narrated Sulaiman bin Yasar
I asked `Aisha about the clothes soiled with semen. She replied, "I used to wash it off the clothes of Allah's Messenger (ﷺ) and he would go for the prayer while water spots were still visible. "
